I think the point is that rather than defining a URI scheme for VWRAP-implementing virtual worlds in general - which might imply namespace management and/or conventions and organization (i.e. you MUST have named regions, you MUST use x/y/z coordinates, you MUST ...) we allow the service provider to offer any URI scheme but standardize on a payload that is compatible with the place-agent-in-region part of VWRAP. For example, Linden Lab offers SLurl.com for Second Life addressing. The fact that visiting http://slurl.com/Ahern/128/128/20 provides a redirect to secondlife:///Ahern/128/128/20 (and the SL client is registered to handle the secondlife: scheme) is an implementation detail. Implementing new schemes is frowned upon. The preferred approach is to return a document with the correct Internet Content Type and have an application register to handle the content type. (i.e. what Meadhbh said!) So we *still* have URIs, but the URIs are real honest-to-goodness HTTP(S) URLs that return actual documents. (You can imagine a trivial redirect site that transforms the URL structure into an LLSD document for a known parameter set.)
